The newest health fad: Fat-infused water

It's time to say what's shaking to Fat Water, the latest lardaceous drink from the creator of Bulletproof Coffee. While its name sounds like a triple-dog dare, the brains behind it, biohacker Dave Asprey, assures everyonethese bottles will be "a disruptive technology for beverages." He says the trick to boosting energy without a sugar crash is mixing two grams of coconut oil (about a tenth of the day's saturated fat) into perfectly fine water. The oils enhance thermogenesis, which is a fancy word for fat burning. "They get burned as energy and have an appetite-suppression effect," he says, adding: "It's not like we put in sunflower oil or canola."

The concoction will no doubt have its devotees, possibly several from among the Silicon Valley fad-diet-market disruptors, who recently dropped $9 million into Asprey's burgeoning Bulletproof café chain, but taste-testers so far are describing it as "liquid soap" and "like Crystal Light not fully diluted." But taste isn't something the food-as-joyless-sustenance crowd has ever cared much about, though.

For now, the product is exclusive to Bulletproof cafes, his website, and a couple of L.A.-area health stores, but Asprey says his oily H2O will be sliding into mainstream stores across the U.S. very soon.
